Heart Interface HF12-1200 - Installation Procedures; Ground Connection

-
Ttg ilverter is
provided
with mounting
flanges
to allow you
to
secure
the
unit. Keyhole
shaped holes in
the
mounting
flanges
will facilitate
mounting
on a wall
or bulkhead.
When
bolting to
either
a
shelf,
a
wall
or bulkhead
use
U4
inch stainless
steel
bolts with
lockwashers.
Tighten
to 2O-25 ft./lbs.
of torque. You
will notice
that
this compresses
the
rubber
feet
somewhat. This is intentional.
INSTALLATION PROCEDURES:
For marine installation,
all
cable and wires
used
in
these
procedures
should
be stranded
and
should meet
United States
Coast Guard regulations.
There
are rhree major
steps in
the
installation
procedure.
Each
step
is
described
and discussed
below. Please
read
the
entire
procedure
before beginning the
installation.
First:
Connect the
ground
Second: Connect
the
AC
oufput
Third:
Connect the
battery
bank
GROUND
CONNECTION:
You must
begin the electrical
installation
by
grounding
the unit to
either
an
earrh
ground
(fornon-mobile
land installations),
or the vehicle
chassis
(for
RV
installations)
or the vessel's
grounding
system
(for
marine
applications).
On the back
of the inverrer
you
will
find
a
connector
labeled
CHASSIS
GROUND.
This is
for
the
purpose
of connecting
the chassis
of
the inverter
to
ground.
You
will
also
find
an identical
connecror
labeled
eqUIPUENf
GROUND. Thisisfortheplrpo_seof

The
CHASSIS
GROUND
andEQUIPMENT
GROUND
are electrically
bonded
togeitrer.
Use
a
green
insulated
8
AWG
stranded
copper
wire
for
your ground
wire.
PROCEDURE:
1.
Measure
and cut the required
length
of
ground
wire for
your
parricular
appli-
cation.
2. Remove
114 inch
of insulation
from
one
end
of the
ground
wire
and insert
the
bare
copper
wire
into
the hole in
the
ground
connector.
Use
a flat
blade
screwdriver
to tighten
down
on
the connector.
Be
sure
the
connection
is
very
solid.
3. Attach
to
other
end
of the
green
wire to
the selected grounding
location.
This
will
vary
depending
on
the installation.
Discussion:
will
be
either
a water
pipe
or a
copperrod
pounded
into the ground
or an
existinfground
rod.
In
a vehicle
connect
the wire
to
the vehicle
chassis.
Make
surc
the
connection is
electrically
sound- Also
make
sure that
your
selected
site
is
electrically
anached
to the
chassis
itself.
Some metal parts
on
some
vehicles
are electrically
isolated
from
the frame
by
rubber
or
plastic
mountings
